mtd/ps3vram: Cleanup ps3vram driver messages
Cleanup the ps3vram driver messages. Add a new struct device pointer variable dev to struct ps3vram_priv and use dev_dbg(), pr_dbg(), etc. where appropriate. Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
